TWO CASES OF CLOUD COMPUTING SOFTWARE AS A SERVICE AND STORAGE AS A SERVICE ECLT 5820 – Distributed System (Group 7) Lin, chen Tso, Sze Hon

Introduction Two Cases: Cloud Computing in MMOGs Cloud Storage What is cloud computing? 23/9/ ECLT Distributed System (Group 7)

CASE I - CLOUD COMPUTING FOR MASSIVELY MULTIPLAYER ONLINE GAMES (MMOGS) 23/9/ ECLT Distributed System (Group 7)

Background The development of MMOGs The revolution chance for MMOGs 23/9/ ECLT Distributed System (Group 7)

Problems & Needs Problems 1. Server capacity 2. Battlefield capacity 3. System requirement Needs 1. All players are in the same server 2. thousands or even millions characters are playing in the same scene as the real battlefield 3. Any PC or game console can play any game 23/9/ ECLT Distributed System (Group 7)

The Principles of Cloud MMOGs Four categories for MMOGs: 1. Virtual Players 2. Virtual non-player characters (NPCs) 3. Movable objects 4. Decorations 23/9/ ECLT Distributed System (Group 7)

The Principles of Cloud MMOGs Cloud game 23/9/ ECLT Distributed System (Group 7)

The Challenges of Cloud MMOGs Bandwidth requirement and occupation Latency and processing time 23/9/ ECLT Distributed System (Group 7)

The Real Practice of Cloud MMOGs & Future Development The alternative way to partially achieve cloud computing in MMOGs 1. P2P sharing 2. Contribution and becoming the composition of whole cloud The future Full version of cloud MMOGs 23/9/ ECLT Distributed System (Group 7)

CASE II – CLOUD STORAGE 23/9/ ECLT Distributed System (Group 7)

Background Storage is cheap People collect & accumulate “stuffs” Rise of mobile device (e.g. tablet, mobile phones…etc) Network technology (e.g. Wi-Fi, WiMax, 3G…etc) Cloud computing allows easy accessibility and ubiquitous computing 23/9/ ECLT Distributed System (Group 7)

Problems & Needs Problems 1. Limited in scalability (e.g. IDE slots, facility space for dedicated server) 2. Costly and complicated for maintenance, scaling, hosting, administrating, and security 3. External storage are bulky, limited in storage space, and easy to damage/stolen/loss Needs 1. Easy access of a reliable secure storage system 2. Less drag for business people who travels the world 3. Mobile device to reach the content via internet 23/9/ ECLT Distributed System (Group 7)

Advantages of Cloud Storage Reliability % uptime Replication of data across the wide network of datacenters Scalability On-demand services Pay as much as you need Simplicity Cloud storage operator automatically configures the amount of resources you need Cost Efficient No upfront investment cost Security Defend against DDOS; due to replications Provide security solution 23/9/ ECLT Distributed System (Group 7)

Advantages of Cloud Storage Examples 23/9/ ECLT Distributed System (Group 7)

Challenges of Cloud Storage Network availability What happen if the company loses internet connections due to network provider’s technical problems or natural disaster? Performance of transmitting data latency issue, tolerable? Security Data location? Any Phishing site? Physical security? Trust issue Leakage of sensitive data information? Other concerns Fail to pay utility, would result in data loss? Who owns the data? 23/9/ ECLT Distributed System (Group 7)

Challenges of Cloud Storage Third-party cloud storage point of view: Reduce in electricity bill Develop energy-saving algorithm Purchase & install energy-efficient hardware Select datacenter location Geographic demand of service Electricity cost Physical plant security requirement Geographic properties (e.g. natural disaster, revolutions?) 23/9/ ECLT Distributed System (Group 7)

The Real Practice of Cloud Storage & Future Development Maximize coverage area for cloud services Focus in Ethical business practices Better integration in media playback Further research reduced power consumption Nanotechnology, solid-state drives (SSDs), advance cooling, and energy saving algorithms 23/9/ ECLT Distributed System (Group 7)

Conclusion Two Cases: Cloud Computing in MMOGs Cloud Storage Question? 23/9/ ECLT Distributed System (Group 7)
